Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76866, here are decompositions:

19 + 76847 = 76866
29 + 76837 = 76866
37 + 76829 = 76866
47 + 76819 = 76866
89 + 76777 = 76866
109 + 76757 = 76866
113 + 76753 = 76866
149 + 76717 = 76866

Showing the first eight; more decompositions exist.
